I have the same problem, ore at least more or less.
I used https://presscustomizr.com/snippet/adding-an-html5-search-form-in-your-wordpress-menu/ to add a searchform behind a magnifying glass symbol to the top navigation menu, but the symbol has disapearded, showing the text “fl” instead.
Mnm’s solutions don’t seem to work:
– clearing browser cache and – history or visiting the website in any other browser makes no difference. I do not use a caching plugin.
– Appearance -> Customizr -> Advanced Options -> Front end icons ( Font Awesome ) still has the checkmark.
I also tried to change the link to the magnifying glass icon from \f002′ to other numbers. This will change it into different “chinese looking symbols.
Could it be that the (free) fonts are excluded from the new version of Customizr?
Any other sugestions?
Thanks in advance for any help…
